The History of the Thurtell Family done by Susan Persia Thurtell about 1968 and the family tree done by Harriet Thurtell about 1900 show George Thurtell died March 16, 1854, at 70. He was married three times. His first wife, Phoebe, died at age 30. He had one child with Phoebe. He and his second wife, Elizabeth Jenner, had three children. Elizabeth died October 17, 1846, at age 60. George and his third wife, Harriet, had no children.

Information received in 1997 from Peter Murray shows that George Thurtell was born in 1784 in Flixton and baptised January 17, 1785, in Blundeston. Three earlier brothers also named George died young, baptised August 7, 1775, and in 1777 in Blundeston, and in about 1780. This George Thurtell died March 16, 1854, aged 70. By the terms of his father's will, proved 1801, income from his father's property at Hempnall Norfolk was to provide for his upkeep and education until he reached the age of 21, and afterwards to be sold and the proceeds of the sale to be divided among the children of James and Winifred Thurtell or their heirs. George Thurtell inherited his father's leased property in Flixton Parish, apparently jointly with his brothers. The 1841 and 1851 census records show him as farmer of 400 acres in that parish, employing 14 outdoor labourers in 1851. He lived at White House, Flixton, and was one of the three chief constables of the Mutford and Lothingland hundred. Elsewhere he is stated to have been "of Lodden Hall" (document in Mickle Collection, Guelph), but this has not been confirmed (although the church at Lodden apparently has Thurtell graves).

He first was married in Lowestoft on October 21, 1807 (parish records say October 27, 1807) to Phoebe Cleveland, who died October 29, 1810, aged 30. He was married for the second time in Gunton, Suffolk (also recorded the same date at Ashby, Suffolk) on January 6, 1814, to Eliza Jenner, who was born in 1786 and died October 17, 1846, aged 60. He was married for the third time, before 1851, to Harriet Jenner, who was born at Lound, Suffolk (sister of Eliza), and who was aged 59 in 1851.

George Thurtell, wives Phoebe and Eliza, and daughters Sarah and Phoebe, are buried at the church in Blundeston.
